Micron has hired a former senior executive from Nvidia to manage its expansion of memory chips for tablets and smartphones. Michael Rayfield, who left Nvidia last month, will take the role of Micron's vice president of Wireless Solutions Group.

He will be in charge of DRAM and NAND flash chips for mobile devices. Rayfield was heavily involved in Nvidia's ongoing expansion from its core PC graphics chip business into mobile devices with its Tegra processors.

Micron is looking for new ways to make cash with PC sales barely growing. The plan is to follow Samsung Electronics and other memory chipmakers as they look at chips for tablets and smartphones.

Data released last week by market research firm IHS iSuppli showed that for the first time since the 1980s, personal computers no longer account for the majority of demand for DRAM memory chips,

Former Intel employee Biswamohan Pani has been found guilty of stealing company secrets and he will have to do a three-years prison stint for it.

Pani stole chip design and manufacturing documentation that’s took an estimated $200 to $400 million to develop. Interestingly, he did so just after announcing his resignation and prior to taking a job with AMD, so we’re not sure whether to call it cunning or just plain daft.

He pleaded guilty to wire fraud back in April. He will do three years in federal prison and two year probation, in addition to a $17,500 fine. AMD claims not to have known about Pani’s plan and the company cooperated with investigators.

Infinity Ward departee, Robert Bowling, has finally announced what his new studio will be working on. Bowling’s new studio, which is known as Robotoki, is working on a new title with the central focus around Zombies and survival; it will be called Human Element.

Human Element is in development for the PC as well as the next generation of console systems. It is planned for a 2015 release. (Yes, developers are already planning for titles that are going to be released in 2015.)

Human Element will be an action-focused title that allows players to experience a number of skill sets while trying to achieve a common goal. A publishing deal for Human Element was not announced, but it is expected to be announced at a later date.

In her first interview since she got the boot, the now former Yahoo CEO Carol Bartz went ballistic against the Yahoo board.

Apparently, Bartz said “These people f***** me over”. She also said that the manner of how she got axed was quite cowardly, as Yahoo chairman Roy Bostock did it over the phone.

Bartz claimed that she told Bostock off, accusing him of not having the balls to tell her face to face and telling him that she thought he was classier. Strangely enough, Bartz will remain on the board, although she did find the time to call her director colleagues doofuses.

To be fair, Bartz did well during her tenure by slashing costs and increasing profit margins, but she failed to improve revenue growth at a critical time.

Sony has hired a former director of the US National Cyber Security centre to sort out the security mess on its Playstation networks.

Philip Reitinger's official title will be senior vice president. He'll be based in Washington and will report to Sony general counsel Nicole Seligman.

Sony has admitted to Reuters that the hacking of its Playstation networks was a catalyst for the appointment. The outfit needs to bolster its network security even further.

Sony shares have tanked since the April hacking, having fallen 55 percent. The hacking generated shedloads of bad publicity and made Sony's planned expansion in online businesses a non-starter.

Reitinger has good contacts. He worked for Microsoft and the US Department of Defense. Apparently he will be based in Washington.

U.S. National Cyber Security Center is part of the US Homeland Security. Its own history of tackling cyber security threats has been mixed. There have been a number of high profile hackings which have been attributed to “foreign actors”and we do not mean Daniel Craig.

Whether Reitinger's national security experience will be a help remains to be seen. Last we heard, Sony did not have the power to break down a hacker's door, bundle him into a car, fly him to a country which will turn a blind eye, while an agent waterboards him.

Jobs' Mob has come up with a novel method of claiming that it invented everything. In amongst the ITC court papers in the recent HTC versus Apple spat is an argument which claims that Andy Rubin got inspiration for Android framework while working at Apple, hence infringing an Apple API patent.

This means that Android started at Apple, just by virtue of the fact that one of its former employees happened to have invented it. If this logic was applied, it would mean that it did not matter where an employee worked in their life all their inventions would be legally owned by the first company they worked for.

Apple told the ITC that Android and Rubin's relevant background does not start with his work at General Magic or Danger in the mid-1990s. Rubin began his career at Apple in the early 1990s and worked as a low-level engineer specifically reporting to the inventors of the '263 [realtime API] patent at the exact time their invention was being conceived and developed. It is therefore no wonder that the infringing Android platform used the claimed subsystem approach of the '263 patent that allows for flexibility of design and enables the platform to be "highly customizable and expandable".

Now if people said that Apple invented Android, they would put them away. But Apple is claiming that Rubin's superiors at Apple were the inventors of that realtime API patent and he worked for them at the very time they made that invention. If the ITC buys this argument then the whole patent system will collapse as many people in the tech industry go on to invent things for other companies. Most people are expected to have learnt something from working in a company, and that is what job experience is all about. However Apple is is one of the few companies that believes it owns its employee's ideas long after they have left the company.

AMD's former Chief Executive Officer Hector Ruiz has opened a consulting company, aiming to win business by touting his experience in leading strategy and transactions.

We guess he will not be mentioning tablets and mobile computing which is the reason that AMD's board asked him to clear his desk. We guess he would also be an expert on Insider-trading as he recently was a witness for the prosecution of Raj Rajaratnam, co-founder of Galleon.

Rajaratnam said that Ruiz was a source of information on transactions by AMD that were then used as the basis of insider trades. Ruiz was never charged with any crime.

Ruiz's company is called Bull Ventures and it has been formed with another AMD bloke Bharath Rangarajan. None of them has commented about the move, but forming the company appears to be Ruiz’s return to business.

According to the company website, Bull Ventures aims to provide advice to companies who want to “grow from good to great.” The company says it helps corporate management teams develop and execute “industry changing strategies.”

Norio Ohga, former Sony president, CEO and chairman who played an important development role in the acceptance of CD formats has died. He was 81.

Ohga, was a senior advisor and former president and chairman of the Sony. In 1982 he was Sony's president and added the position of CEO to his title in 1989, the same year Sony purchased Columbia Pictures. He retired in 2003.

One of Ohga's greatest achievements was he spearheaded Sony initiative to develop CDs. As a former musician, Ohga wanted CDs to be large enough to listen to Beethoven's Ninth Symphony all the way through without stopping. This explains why CDs could contain more information than was required for pop albums at the time.
